well the real meaning is one who bakes clams on a beach, but as I was searching for another word for Fag, this word came up under my search box, so therefore, rather than saying "Hey take your fucking hands off me you fag" you can simply say "hey take your fucking hands off me clambaker"

So therefore, Clambaker means one who is homosexual or just a fucking loser/turd/jackass/cunt/cock and so on.
